I have a conundrum. I have had daily headaches for the past 5 weeks or so. They are significant headaches, not nagging, more like harassing. I don't remember when they started exactly, but I do remember being surprised when I didn't have a headache on Oct. 22nd. I would guess that it had gone on consistently for about 7-10 days prior to that. They start in the early afternoon and ramp up to their worst before dinner. After dinner they usually seem to fade away.
Additionally, around 2pm I have been developing insulin resistance and my glucose rises to about 200 and stays there until 12midnight. During the night it slowly eases back to normal and is always 100-120 normal when I wake up. According to my sensor, it never goes hypo.
One theory to consider is that the headache and the glucose rise are related, and that they are triggered by the Somiyogi Effect. I have had periods when my basal insulin wasn't right overnight and I would go low and then bounce back on a "rebound" for about 6 hours of BG at 180-250 (AND a regrettable headache usually hangs around for several hours).
So... I have considered a few factors and done a few experiments to see if I could stop them.
1) Food: I wondered if intermittent fasting was causing some sort of hormonal event that triggered cortisone or something that might bring a headache and insulin resistance along. I tried eating breakfast, more carbs, more protein, etc. and nothing has seemed to help. The headaches have been the most consistent thing lately...
2) Hydration: I am guilty of neglecting my hydration on days that I am busy at work. I am certain that there have been days that I've given myself a headache from dehydration. However, I have made an effort to drink plenty of water throughout the day many days in the past 2 weeks, and haven't seen a difference.
3) Tea: I noticed that the routine headache was also synchronized with my 2nd cup of strong tea for the day. Some research on the web showed that some people are sensitive to black tea and get the achey neck and head that I was having. I stopped drinking tea altogether for a week, and I still had headaches (maybe a different type?). However, when I drank tea, they seemed to get worse, or be compounded. Inconclusive... I really love my black tea.
4) Supplements: A while ago, (maybe a month?) I ran out of Alpha Lipoic Acid, and have been living without it. It is a insulin mimetic that reduces my insulin requirements. I expected to increase my basal, but didn't really notice anything change, except this insulin resistance in the PM hours. I have gotten another shipment of ALA and am taking as I had before. I'm looking to see if my BG levels out and stays constant all day, as it did from Aug-Oct.
I have heard that low-Magnesium can cause headaches. So I added Magnesium to my list of supplements. I also added vitamin D and A.
5) Workplace: On Oct. 22nd I realized that I hadn't had a headache that day. It was a day we had a field trip, and I hadn't spent the day in the building where I normally am. I also didn't have tea that afternoon. Maybe something is wrong with my school building? *This weekend, I was waiting for the headaches to hit at their normal time, and they didn't. My BG did rise, as it has lately, but I didn't have the headaches. Right now this seems to be the most likely cause of the headaches... but, unfortunately, it's the issue I have the least ability to solve. I am wondering what types of factors in my school building could cause the headaches. During the weekend I did consume tea and cider with no ill-effects.
6) Eyes: I had my vision checked this summer and didn't have a significant change in my prescription. When I wear my contacts all day they start to bother me, but I've been off the contacts for a while.
7) Cider: I have been having a nightly pint (or two) of home-brewed hard cider for roughly the same amount of time that this has been going on. It didn't occur to me to consider it as a suspect until I was working through this list. I may have to take a few days off to see if it's a possible culprit. Last winter it was also my beverage of choice and I don't remember anything strange during that time... then again, my BG control wasn't amazing then either.
So, that's my list. I am wondering what I'm missing. If I am a typical T1 diabetic, I have a tendency toward autoimmune problems. I wonder if I could be doing something to aggravate my immune system and create some sort of domino-effect. Could I be a migraine person, sensitive to dark chocolate, coffee and red wine?
